在XML / XSD模式文件中，我们如何从元素中提取（解析）某些信息？

问题描述 投票：0回答：3

是否有一种方法可以解析XML文件中的某些数据，然后将该信息输出到excel（csv）文件中？我想知道是否可以在C＃.NET应用程序中将其自动化，而不是手动浏览XML文件并在excel工作表中对其进行更新。这样，如果我有许多XML文件，则可以运行该应用程序以获取所需的信息。

例如，假设XML文件中存在此元素：

<element type="xpowercomponent_FeaturedTiles" UID="40204fc9b5424b349e03134d777d29bc" label="Featured Tiles" readonly="false" hidden="false" default="" required="false" Component="" CompTypes="ThemedTileSetComponent;ThemedTileSetElectedComponent;" AutoEmbed="" WrappedUp="" AllowWrappingChange="" />

我正在尝试从XML文件的each元素中提取的数据是，元素：类型，标签，CompTypes，只读，隐藏，必需。

我已经尝试执行以下操作，但是由于对XML的使用不太熟悉，因此不确定该方法是否可行。 

static void Main(string[] args)
    {
        XmlSchemaSet schemas = new XmlSchemaSet();
        schemas.Add("", XmlReader.Create(new StringReader(File.ReadAllText("Schema.xsd"))));
        schemas.Compile();
        AnalyseSchema(schemas);
        Console.ReadLine();
    }
}

XmlSchema customerSchema = null;
        foreach (XmlSchema schema in set.Schemas())
        {
            customerSchema = schema;
        }

这里是完整的XML模式文件：

使用此代码。您需要将xmldocument转换为xdocument。因此，您可以轻松捕获每个元素及其数据。我使用了您提供的相同文件。我还提到了如何读取循环及其子元素的示例。

class Program
{
    static void Main(string[] args)
    {
        Parse();
    }

    public static void Parse()
    {

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(@"D:\New Text Document.xsd");

        var xdocument = xmlDoc.ToXDocument();
        foreach (var element in xdocument.Elements())
        {
            foreach (var node in element.Elements()) //childs...
            {
                if (node.Name.LocalName.Equals("objectId"))
                {
                    // obj.Id = node.Value;
                }

                if (node.Name.LocalName.Equals("name"))
                {
                    //obj.Name = node.Value;
                }

                if (node.Name.LocalName.Equals("scope"))
                {
                    foreach (var scopeNode in node.Elements())  //more childs
                    {
                        if (scopeNode.Name.LocalName.Equals("id"))
                        {
                            //  obj.ScopeId = scopeNode.Value;
                        }

                    }
                }
            }
        }
    }
}
public static class DocumentExtensions
{
    public static XmlDocument ToXmlDocument(this XDocument xDocument)
    {
        var xmlDocument = new XmlDocument();
        using (var xmlReader = xDocument.CreateReader())
        {
            xmlDocument.Load(xmlReader);
        }
        return xmlDocument;
    }

    public static XDocument ToXDocument(this XmlDocument xmlDocument)
    {
        using (var nodeReader = new XmlNodeReader(xmlDocument))
        {
            nodeReader.MoveToContent();
            return XDocument.Load(nodeReader);
        }
    }
}

非常容易在XSLT中完成。您不需要架构。除非有特殊的字符需要转义，等等，它很简单：]

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="3.0" expand-text="yes">
<xsl:mode on-no-match="shallow-skip"/>
<xsl:output method="text"/>  
<xsl:template match="Element"
>{@type},{@label},{@CompTypes},{@readonly},{@hidden},{@required}
</xsl:template>
</xsl:transform>

这是XSLT 3.0解决方案；如果您更喜欢使用.NET附带的XSLT 1.0处理器，则它比较冗长，但仍然非常简单。我没有包括标题行，但是添加它很简单。

在XSLT 3.0中，您甚至可以添加自动化功能以将其应用于整个XML文件集合（在1.0中，您需要在调用脚本中执行此操作。

在C＃中，使用System.Xml.XmlDocument和SelectNodes中的XPath语法

XmlDocument xml = new XmlDocument();
xml.Load( strFile );
foreach (XmlElement ndRow in xml.SelectNodes("//element")) {
    string strType = ndRow.GetAttribute("type");
    string strLabel = ndRow.GetAttribute("label");
}
